According to the Wall Street Journal, Japanese customers -- especially men in the 18-30 age bracket -- are going wild for these All-American burgers. In fact, their popularity is particularly ironic given 1) the Japanese are traditionally more slender and have healthier diets than Americans; and 2) McDonald's here in the States is making a concerted move toward more healthier menu items like salads and oatmeal.

Yet, there are some factors working directly in McDonald's Japan's favor, which might explain the success of these burgers. First, Japanese customers are suckers for anything that's offered for a "limited time" -- and that's exactly how these burgers are being marketed.

Moreover, fast food has yet to be vilified in Japan like it is in this country. In other words, it's still cool to get excited about fast food in Japan.

Still, I'd appreciate a disclaimer in the McDonald's advertisements for these burgers that assures the people of Japan that not all Americans eat like this every day and not all of us put tortilla chips on top of our burgers.
